IMPACT MODIFIED POLYMERS |
摘要 |
Impact-modified polymeric materials are produced by visbreaking certain reactor blends. In a preferred embodiment, impact-modified polypropylene materials are produced by visbreaking a reactor blend of polypropylene and thermoplastic polyethylene. The polypropylene material is preferably homopolypropylene having a melt flow rate of less than about 1 dg/min. Such impact-modified polymeric materials manifest unexpected compatibility characteristics, increased impact resistance at low temperatures, improved antiblush characteristics and improved flow characteristics. |
